Virtualization for aggregation combines
physical servers and their memory and CPU power to create a single, large
virtual machine
In computing, a virtual machine (VM) is the virtualization/ emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized har ...

Virtualization for aggregation is the opposite of traditional
server virtualization, which partitions a single physical system so that multiple
OSes can be run on the hardware. The technology is primarily used to run compute-intensive applications on a virtual
symmetric multiprocessing
Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all ...
(SMP) system, and can benefit users who want to provide very large memory and capacity resources for
high-performance computing
High-performance computing (HPC) uses supercomputers and computer clusters to solve advanced computation problems.
Overview
HPC integrates systems administration (including network and security knowledge) and parallel programming into a multi ...
(HPC) needs without having to invest in proprietary SMP systems, which are beyond the reach of many users.
